Given numbers are 306, 847, 626, 638

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(306, 847) = 259182

GCD(306, 847) = ( 306 x 847 ) / 259182

= 306 / 847

= 306

Step2:

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

= 1 / 626

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 306, 847, 626, 638 is 1
